These are some of the questions that may arise in the minds of students about independent variable in math such as “what is the independent variable in math”. And why do we need independent variables in experiments or other contexts? Also, is there any point in understanding independent variables?
As a result, to assist these students, we have put together a comprehensive guide on what is an independent variables in math and can get math assignment help. As you will see, we have provided some examples below to inspire your learning. And also to give you an insight into the independent variables concepts. So, let’s get started.
What is an Independent Variable in Math?
Their values are individualistic and are responsible for causing the changes independent variables. Independent variables are, as their names suggest, independent of factors outside themselves.
Important Takeaways: Independent Variable
The following are some key points to help you understand what is independent variable in math:
- To find out the effect of something you change or control, this is known as the independent variables.
- A dependent variable is a variable that reacts to changes in an independent variables.
- An x-axis plots the independent variables.
Let’s look at an example:
We can now say that speed (distance/time) is a dependent variables, and both distance and time are independent variables, to determine the speed of a car.
You can change the speed and distance independently. If you want to cover a distance of 15 km, you can increase speed and decrease speed separately.
This is why time and distance do not depend on each other, but speed does.
What are the proper ways to write dependent and independent variables in an equation?
In linear regression, we need a linear equation that includes only one independent variables. As you are already aware, linear regressions rely on the linear equation.
As a result, we have the following linear equation:
y = a+b*x,
=> The variables y and x are constants in this equation. Additionally, a and b are two constant numbers.
A straight line will be drawn if you draw y = a+b*x.
Where do you find the independent variable?
The dependent and independent variables always appear in the same places on the graph after you know what an independent variable is in math.
Graphs are useful in verifying and understanding which variable is independent and which is dependent.
The horizontal axis or x-axis is used to plot an independent variable, while the y-axis is used to plot the dependent variable.
Let’s examine an example: (A graph from Enna’s score)
The following are some example to help you understand what is independent variable in math:
In the graph above, it is evident how the score increases as the number of study hours increases. Enna gets a higher score in her exams when she studies for 6 hours. But, her score went down slightly when she studied for more than 6 hours.
Rather than explaining Enna’s performance, we aim to make you understand what independent variables in math are instead of showing you why her score was dropped.
Consequently, by looking at the graph below, you can see that time represents the independent variable, which has been changed. Therefore, time appears on the x-axis. And score represents the dependent variable. This is represented on the y-axis.
Observing the graphs of a linear or algebraic equation can help you find the independent variables by simply noting how the dependent variable changes with the value of the independent variables.
Here is a quiz to test your knowledge about the independent variables!
Imagine being assigned the task of finding the popcorn brand that has the most kernels in its bag. You tested various brands’ bags to determine the most kernels in a bag.
So, what are linear the independent variables and dependent variables in this experiment?
Solution:
The brand of popcorn bags is an independent variables because you need to choose the brand of popcorn bags.
Variable dependent: The kernel pops are the things that your brand needs to be ranked.
Final words:
Among the frequently searched questions in math is what is an independent variable in maths. Independent variables are, as their names suggest, independent of factors outside themselves. You can change the speed and distance independently. This is why time and distance do not depend on each other, but speed does. In linear regression, we need a linear equation that includes only one independent variable. As you are already aware, linear regressions rely on the linear equation. The variables y and x are constants in this equation. The dependent and independent variables always appear in the same places on the graph after you know what an independent variable is in math.
